 /**
  * Standard workbench wizard that create a new file resource in the workspace.
  * <p>
  * This class may be instantiated and used without further configuration;
  * this class is not intended to be subclassed.
  * </p>
  * <p>
  * Example:
  * <pre>
  * IWorkbenchWizard wizard = new BasicNewFileResourceWizard();
  * wizard.init(workbench, selection);
  * WizardDialog dialog = new WizardDialog(shell, wizard);
  * dialog.open();
  * </pre>
  * During the call to <code>open</code>, the wizard dialog is presented to the
  * user. When the user hits Finish, a file resource at the user-specified
  * workspace path is created, the dialog closes, and the call to
  * <code>open</code> returns.
